Replaced by an internal 50pin, but I plan to make plugin add-on with Falcon HD DSUB.

SDMA, Combel, Videl. Everything else is generic and available.

Re: falcon Testkit

Yes, and no at the same time. Máté Sebők has managed to debunk the DSP dongle pinout for 1.21 rev. test SW, but 1.27b rev. breaks that compatibility.
So we now have a dongle that 1.21 test kit SW passes with, but we do not have one for 1.27

There is more you need to hack in your STe, then closing the solderpad, if you want it to read HD FDD and that includes Gotec emulated one. read i.e. here: https://www.exxoshost.co.uk/atari/last/floppy/index.htm

Re: Beginning of very long journey

VCC done, now there is just a 120 unrouted GND connections left. Then the last thing to do is to check those few inner layer tracks and maybe re-align them, do a manufacturing capability check and I am done with a design.

Re: Beginning of very long journey

Just a quick update on a progress: I have cleaned up the silkscreen (unimportant but funny part) and I am about 50% done with VCC interconnections.
Oh yes, that bug in schematic is now fixed too.

Re: Overheating chip on Atari STE plugged into socket U405--is it normal?

Doesn't seem right. That's an electrolytic capacitor and I see no reason why it should become hot unless its damaged, the polarity is incorrect or it's exposed to ripple currents that's outside of its specifications, etc. In general, electrolytic capacitors should not be exposed to high temperature...

Re: TT 030 can't run Jinee (and some other apps) - two bomb bus error

PSU - +5v and +12v are bang on and stable - so far so good: you can not say this without a scope. Capacitor visual inspection is not sufficient, they are slowly drying and failing.IMO you are dealing with either failing memory chip, or failing power supply, caused by failing capacitor(s).

Re: Dead Falcon - no boot / coloured screen only

Did you check for any physical damage? Probably small, possibly from a desk drop/tumble. Broken solder points? Check with a magnifying glass, 10x or better. rarely do falcon chips go bad. Possible but unlikely. Your symptoms suggest something physical, in my very small opinion. Perhaps do the 'bake...

What does that mean?

Right. What I meant is there is no COTS AC/DC power supply that is known to be compatible with CT60. Basically, none of them (to my knowledge) works.
